I started Wikipeding in April 2010 by expanding a stub related to a village in North Lincolnshire (Alkborough). This is an ongoing project. However, my main interest is in the Roman Empire, and specifically Hadrian's Wall. I'm currently involved in a little project-ette to create entries for each of the Milecastles along Hadrian's Wall. It takes much longer than you might think!
First impressions of Wikipeding? There's always more that you want to do, than time you have to do it.
All Wikipedia pages, including articles and user pages alike, have a corresponding Talk page. To switch to the current page's Talk page, click on the "Talk" tab above the page's title. At the very top of the page there is always a link to your Talk page.
All content and conduct issues should be discussed at either the article's or user's Talk page before requesting dispute resolution.
You can {{ping}} specific editors whom you would like to notify of your message post. Though there is no need to ping someone when you've edited their Talk page, because the Wikimedia software automatically notifies that user.
